This is one of the most cogent presentations I’ve ever read about EBS spectrum. Thanks for tweeting the link to @danxoneil.
Take a look at a map of the service areas assigned to licensees in the Educational Broadband Service (EBS). You might expect to see a coherent pattern of similar coverage areas effectively blanketing, in the aggregate, entire states (perhaps even with particular stations’ contours coterminous with state boundaries). You’d be disappointed. What you’ll see instead is a crazy quilt of circles, trapezoids, crescents, half-moons, triangles – shapes differing from channel to channel. And beyond that, there are multiple areas that don’t happen to sit within any EBS station’s coverage. (via EBS Industry Players Push For Expanded GSAs, New Filing Windows : CommLawBlog)
